I Claims. 1;

Thisinvention. relates tohose reeling mechanism. More specifically; it.is concerned with hose reeling mechanism. intended to be used indispensing petroleum products like gasoline or oil at airports inservicing planesand other'fiy-ing craft.

In hose reeling. mechanism, as ordinarily constructed, the reel onwhich: thehose is wound is horizontally arranged; and in instances wherethe liquids are metered, the sealers require the hose to bedrained'after each delivery toprevent cheating of the purchaser. With.a. horizontal reel however, some off the liquid. will: always: remain inthe bottom of thelconvolutions or turns ofthe hose. Since trappedliquidacannotbe completely removedby pump action, it isimpossible todetermine, with. any degree of accuracy, any fixed amount that. shouldbe allowed the'purchaser as a deduction from the. reading of. the meterat the time asale is made;

The chief aim of. my'iHV8I1l7iOl1',iS-.t(] overcome the drawbacks towhich reference is madeuabove. This objective isattainedinpracticeashereinafter more fully. disclosed, through.provision: of

an improved hose reeling mechanism. adaptedfor installation in a pitbelow the-.groundlevel, in which the reel is vertically arranged androtatively supported, in which the hose extends up through an aperturein a cover over. the pit, and

in which the reel has aspiral ledgeatthe bottom whereon the lowermostconvolution of the hose is supported with the succeeding convolutionspiled up upon it to insure complete drainage.

In connection witha hose reelingmechanism having the foregoingattributes, it is a further aim of my invention to provideautomaticallyoperative means for guiding and controlling the I hose topredetermine uniform distributionof its turns on the reel duringwinding, as well as to prevent snarling thereof. incident. to withdrawalfrom the pit.

Still another object oiLmy invention is to provide a simple and reliablepower drive means for driving the reel in winding,zwith.means which willallow reverse rotation of the reel by-manual pull upon the hoseinunwinding.

Other objects andtattendant advantages will appear from the followingdetailed description of the attached drawings, wherein: Fig: 1isa-fragmentary view in vertical section of 'a-pitrcontaining myimproved hose reeling mechanism.

As herein exemplifiedmy improved hose reeling mechanismcomprises avertically-arranged reel 5. with a cylindric drum which mayvbeconveniently fashioned from sheetmetal, and with spoked wheel-likeends 6 and 1" respectively at the top and bottom. Extending axially.down into. the drum through av central hub. element 8 of the top wheelend 6 is a shaftBwhereofthe upper end is journalled in a bearing I0.From Figs. 2 and 3 itwilli be notedthat'the bearing I0 is fixedlysupportedv by a channel'beam I I forming part ofastructural ironskeleton framework lzset into a pit l3 below the ground level. At itslower end;.'the shaft 9 is securediin the upstanding. boss l5a, onone'elbow l5 bolted to the bottom head T of the drum 5. The downwardportion of the elbow l5 extends axially through the lower drum head 1and mates with a fixed elbow it, they two elbows together-constitutingwhat is ordinarily known as a swivel'fitting which, in this instance,serves torotativelysupport" the reel 5 at the bottom. The' fixed-elbow[6 of the swivel fittingis weldedor otherwise rigidly se-' cured to across member I! of the framework- 12', and is in communicationbywayofapipe l8 with a source of-supply (not-shown) 1 of the liquid commodity'to' be vended; The" delivery hose'; designated 20,- is connected to-thehorizontal outlet branch-ofthe elbow IS-andcoiledabouttlie drum with itsfree end portion passing tangentially from the drum as in Fig. 2-and-then upward and outward through anaperture -2-l in a cover plate 22that closes the pit l-3 at the top-as in Fig. 1. A spiral ledge 23"having a circumferential ex-tent of about" 270*-periphera1ly of "thebottom head 1 3 wheel affixed to the drum shaft 9 immediately below theupper bearing ID for the latter. The sprocket pinion 28 is connected tothe shaft 21 by a clutch device 3| of a well known commercial typehaving a release plunger 32.

The means which I have devised for controlling the hose 20 to insureeven winding thereof on the drum 5 comprises a flanged wheel which iscircumferentially configured to conform to the cross section of thehose, and which is adapted to roll on top of the convolutions or turnsof the latter as best shown in Fig. 1 during winding and unwinding. Thewheel 35 revolves freely about a horizontal axis stud 36 projectinglaterally from a slide carriage 31 which is constrained to movement onguide rods 38, 39 extending vertically between the horizontal member Hat the top of the framework l2 and a corresponding member 40 at thebottom. As shown in Fig. 2, the carriage 31 is attached to an endlesschain 4| which is trained about sprocket pinions 42 and 43 whereof thelatter rotates freely'about a lateral stud 44 on a bracket 45 mounted onthe frame member 48. The sprocket wheel 42 is afiixed to a horizontalaxis shaft 41 rotatively supported 'by another bracket 48 on theframework, together with a miter gear pinion 49 which is'in mesh with acompanion miter pinion 58 free to rotate about a stud 5| upstanding fromsaid bracket. Secured to the pinion 50 is a sprocket wheel 52 which,through a chain 53, is adapted to be driven from a sprocket pinion 54from the output shaft 21 of motor 25.

As shown digrammatically in Fig. 4, the motor 25 is connected to a threewire electric power limit switch 58 which, see Fig. 1, is secured to the:1

guide rod 39 near the top for actuation of its plunger 59 by thecarriage 31 when the latter is fully elevated and the hose 20 iscompletely wound up on the reel. Also embodied in the wiring system is asolenoid 80 which, see Fig. 2, is supported by a standard 6| from theframe of motor 25 with its armature 62 inaxial alignment with theactuating plunger 32 oftlie clutch"3|, and subject to a spring 63 tonormally hold the clutch released. In order to prevent kinking of the hose2|] as it is passed downward into or upward from the pit andtangentially to or from the drum 5, I have provided a group of guiderollers 65, B8 and 61 which are supported for free rotation by alaterally extending bracket 68 welded to the frame l2 at the top of thelatter.

Although, as already stated, the clutch 3| is of a well known type, itsconstruction will be briefly described in connection with Fig. 5 inorder that its use in connection with my invention may be properlyunderstood. As shown, it includes a drum element 18 which is secured tothe shaft 21 by a set screw 1|. Rotatable about the lower portion of thedrum element 18, with interposition of a pin bearing 12, is a collar 13whereto are bolted the sprocket pinions 28 and 54. Anchored in anannular groove in the top of collar 13 and extending upward about thetop portion of element 10 is a coiled spring 15 whereof the free end isconed. The plunger 32 is slidable endwise in the axial bore of the drum18 and urged outwardly by a biasing spring 16. Extending crosswisethrough theplunger 32 is a pin 11 which is constrained in a diametralslot in the top of the drum element 18, with its ends engaging throughaligned apertures in a ring 18 which is flared to correspond with thecone taper of clutch spring 15. Normally, the collar 13 is free torotate about the drum 10. However upon depression of the plunger 32 andthe ring 18 being brought into engagement with the top of spring 15, thelatter is caused to bind upon the drum 15 with the result that thecollar 13 and the sprocket pinions 28 and 54 will be clutched to anddriven by shaft 21.

Operation With the clutch 3| normally released, the hose cident to whichthe reel 5 will freely revolve on its axis. Through the gearing 30, 29,28, 54, 53, 52, 50, 49 and chain 4|, the carriage 31 will beconcurrently moved downward on the guide rods 38 and 39 for control ofthe hose by the flanged wheel .35. Upon delivery of the desired amountof the liquid commodity, the button of manual switch 51 is pressed tostart the motor 25, with incidental energization of the solenoid 68 andsetting of the clutch 3| for drive of the various gear connections bypower from said motor. Through the gearing, the reel 5 is rotated todraw in the hose 20, while the carriage 31 is compensatively elevated tocontrol, through its flanged wheel 35, uniform winding of the hose aboutthe reel. Eventually, current flow to the motor 25 will be interruptedthrough opening of the limit switch 58 by the carriage 31 when thedesired amount of the hose has been wound upon the As the winding takesplace, the successive convolutions of the hose will be piled one uponanother, all at the inclination determined by the spiral ledge 23 at thebottom of the reel so that complete draining may take place. It is to beunderstod that the push button switch 51 is suitably located forconvenience of ready access above ground.
